Bridgestone develops CAIS-based tyre wear sensor
It’s more than three years since Bridgestone Corporation first announced its work with what it calls Contact Area Information Sensing, or CAIS. When it initially presented CAIS at the IAA Cars show in 2011, the tyre maker proposed the use of the “future technology” for determining road surface conditions. Now Bridgestone says it has developed a system based on CAIS that can estimate tyre wear and tread depth. No timetable for rolling out the technology in volume-production tyres has been announced at this stage.
